Export of BGP Community Information in
IP Flow Information Export (IPFIX)
Abstract
By introducing new Information Elements (IEs), this document extends
the existing BGP-related IEs to enable IP Flow Information Export
(IPFIX) to export BGP community information, including the BGP
Standard Communities defined in RFC 1997, BGP Extended Communities
defined in RFC 4360, and BGP Large Communities defined in RFC 8092.
According to the network operator's BGP community planning, network
traffic information can then be accumulated and analyzed at the BGP
community granularity, which represents the traffic of different
kinds of customers, services, or geographical regions. Network
traffic information at the BGP community granularity is useful for
network traffic analysis and engineering.

RFC 8549 Export of BGP Community in IPFIX April 2019
1. Introduction
IP Flow Information Export (IPFIX) [RFC7011] provides network
administrators with traffic flow information using the Information
Elements (IEs) defined in the "IPFIX Information Elements" registry
[IANA-IPFIX]. Based on the traffic flow information, network
administrators know the amount and direction of the traffic in their
network and can then optimize the network when needed. For example,
the collected information could be used for traffic monitoring and,
optionally, for traffic optimization according to the operator's
policy.
The "IPFIX Information Elements" registry [IANA-IPFIX] defines the
following IEs for traffic flow information export in different
granularities: sourceIPv4Address, sourceIPv4Prefix,
destinationIPv4Address, destinationIPv4Prefix, bgpSourceAsNumber,
